Ukusabela kwe-Aluminium Powder
Ukudonsela phansi okuthile kwe-aluminium kungu-2.7 kuphela. Ngaphansi kwezimo ezijwayelekile, i-1.24 l ye-hydrogen ikhiqizwa ngawo wonke ama-1 g we-aluminium. Ngakho-ke, inani elisetshenzisiwe lincane futhi izindleko ziphansi. Ukukhishwa kwe-aluminium kukhulu futhi umthombo ububanzi. Kusetshenziswa ekukhiqizweni kokhonkolo ongezwe futhi kulula ukulawula ngokwemigomo yenqubo. Yinto esetshenziswa kakhulu ukusetshenziswa kwe-gassing. I-Aluminium iyinsimbi esebenzayo kakhulu. Kungasabela nge-acid ukufaka esikhundleni se-hydrogen ku-acid, futhi nakho kungaphendula nge-alkali ukuze kuhlangane. I-Metal Aluminium i-oxid kalula ukwakha i-aluminium oxide emoyeni. Ifomula yokuphendula imi kanjena:
4o2 22al2o3
I-Aluminium Oxide iqinile emoyeni nakumanzi. Imikhiqizo ye-aluminium esiyisebenzisayo empilweni yethu yansuku zonke inefilimu evikelayo yokuvikela ye-aluminium oxide, evimbela ezinye i-oxidation ze-aluminium yensimbi. Kodwa-ke, i-aluminium oxide ingasabela nge-acid noma i-alkali endaweni ene-acidic noma ye-alkali ukuze wakhe usawoti omusha, abhubhise ungqimba oluvikelayo.
Al2o3 6h = 2AL 3h2O
Al2o3 20h- = 2 A12O3 H2O
I-Aluminim yensimbi ihlangana namanzi, isusa i-hydrogen emanzini futhi yakhiqiza i-aluminium hydroxide.
2-2l 6h2o = 2l (oh) 3 3h2 ↑
I-aluminium ekhiqizayo ye-aluminium esiyisebenzisa kaningi inezinhlayiyana zayo ze-oxidized, yakha ifilimu evikela i-aluminium oxide evimbela i-aluminium ekuxhumaneni namanzi. Kungemva kokuba ifilimu ye-oxide iqediwe amandla e-aluminium poffay aphendule futhi alahle i-hydrogen emanzini. Ngakho-ke, sithi i-aluminium powder, njenge-ejenti eyenziwa yigesi, ingabhekana nokusabela kwegesi endaweni ye-alkaline.
I-AL (OH) I-3 ekhiqizwa ukusabela kwe-aluminium namanzi kuyinto efana negel-efana, evimbela ukusabela okwengeziwe kwamanzi ne-aluminium, kepha i-a1 (oh
Al (oh) 3 oh- = a1o2- 2h2o
Ngale ndlela, endaweni ye-alkaline, i-aluminium ingaqhubeka nokuphendula ngamanzi ukukhiqiza i-hydrogen kuze kuphele i-aluminium yensimbi.
E-slurry ekhonkolo evulekile, into i-alkaline yi-ca (oh) 2. Ngakho-ke, ukusabela kwe-aluminium powder namanzi kungabhalwa njengo:
2ca (oh) 2 6h2o = 3cao? Al2o3? 6h2O 3h2 ↑
UJiangsu Jiali Technology Technology Co, Ltd.is Ifektri etholakala eScaquan, China. Okukhethekile ekukhiqizeni i-aluminium paste, njengokunamathisela kwe-aluminium ngokhonkolo ohleliwe, i-aluminium paste ye-aerated brick, i-aluminium paste ye-ALC Board, njll.
